I checked the M3U and the XML file to verify it is correct. I haven't changed IPTV providers.
Here is what the EPG looks like:
<programme channel="I401.18990.url.org" start="20180905190000 +0000" stop="20180905193000 +0000">
Here is what the M3U for that channel looks like:
#EXTINF:-1 tvg-name="TSN 2 HD" tvg-id="I401.18990.url.org" tvg-logo="/home/iptv_logos/tsn%202%20hd.png" group-title="Sports",TSN 2 HD
Is the issue with my channel not being strictly numerical?
